Each filesystem has its own rules for organizing partition space to store different objects (files, folders, symbolic links, etc.).įilesystem metadata may also contain the deleted file’s name and information about the folder this file was stored in. This partitioning information gives you an understanding of the amount of data in the drive image that should be treated as a single filesystem.Ī filesystem is responsible for storing data in a structured way so that each file can easily be identified and retrieved. The system stores all information about the location and size of each partition in a partition table. Usually, these partitions are created, resized, or deleted when installing an operating system. A drive usually has several partitions - regions that can be managed separately and are treated by the system as distinct logical disks. Knowledge of a disk’s structure is a must for successfully recovering data from a disk image. Related services Enterprise Data Management Solutions Disk structure and data recovery
In this article, we’ll focus on the logical acquisition of data, in which the image of a physical drive is analyzed with special tools and the needed data is extracted from it. Lost or deleted data can be recovered from a corrupted drive in two ways: physically or logically. Or if a flash drive controller’s settings were reset, the drive simply won’t know what the size of a particular memory sector was or how many sectors the drive had.

Data recovery may be partial or even impossible if the data was corrupted due to the malfunctioning of the target device.Įven if the data is intact, recovering it in full may still be impossible if you have no information on the drive’s specifications. There are many potential risks and issues you should be ready to deal with.
